  {
    "question": "根据文档，Spring Bean与一个普通的Java对象最核心的区别在于什么？",
    "options": [
      "Spring Bean必须实现特定的接口，而普通Java对象则不需要。",
      "Spring Bean是由IoC容器负责实例化、组装和管理的。",
      "Spring Bean不能拥有构造函数，必须是无参的。",
      "Spring Bean默认是线程安全的，而普通对象不是。"
    ],
    "correctAnswerIndex": 1,
    "explanation": "文档的核心思想是，普通Java对象需要开发者通过`new`关键字手动创建和管理，而Spring Bean则是由Spring IoC容器来控制其整个生命周期，包括创建、依赖注入和销毁，这也就是“控制反转”的核心理念。",
    "source": "文档中「Spring Bean的生命周期」部分",
    "hint": "文档中提到：'Spring不再自己去new对象了，而是由IoC容器去帮助我们实例化对象并且管理它'。"
  },
  {
    "question": "文档中特别指出，关于Spring Bean生命周期的详细管理主要适用于哪种作用域（scope）的Bean？",
    "options": [
      "prototype",
      "singleton",
      "request",
      "session"
    ],
    "correctAnswerIndex": 1,
    "explanation": "文档中明确强调：'这里我们说的 Spring Bean 的生命周期主要指的是 singleton bean，对于 prototype 的 bean ，Spring 在创建好交给使用者之后则不会再管理后续的生命周期。' 这意味着容器不会调用prototype bean的销毁方法。",
    "source": "文档中「Spring Bean的生命周期」部分",
    "hint": "文档中有一句加粗的文字，对比了两种不同作用域的Bean在生命周期管理上的差异。"
  },
  {
    "question": "依据文档对Spring Bean生命周期的总体描述和源码分析，以下哪个顺序正确地反映了Bean创建过程中的三大核心步骤？",
    "options": [
      "属性赋值 -> 实例化 -> 初始化",
      "初始化 -> 实例化 -> 属性赋值",
      "实例化 -> 属性赋值 -> 初始化",
      "实例化 -> 初始化 -> 属性赋值"
    ],
    "correctAnswerIndex": 2,
    "explanation": "文档中的流程图、列表和`doCreateBean`源码片段都清晰地指明了这个顺序。首先，Spring通过构造函数调用完成“实例化”（Instantiation）；然后，进行依赖注入，即“属性赋值”（Populate Properties）；最后，执行如`@PostConstruct`或`init-method`等方法完成“初始化”（Initialization）。",
    "source": "文档中「Spring Bean的生命周期」和「Spring Bean初始化的流程」部分",
    "hint": "可以类比现实中造一辆车：首先要造出车架（实例化），然后安装各种零件（属性赋值），最后进行调试启动（初始化）。"
  },
  {
    "question": "在文档的“SpringBean生命周期函数分类”中，实现 `InitializingBean` 和 `DisposableBean` 接口属于哪一类？",
    "options": [
      "Bean自身的方法",
      "Bean级生命周期的方法",
      "容器生命周期方法",
      "工厂后处理器接口方"
    ],
    "correctAnswerIndex": 1,
    "explanation": "文档将生命周期函数分为四个类别。其中，“Bean级生命周期的方法”明确包括了`BeanNameAware`、`BeanFactoryAware`、`InitializingBean`和`DisposableBean`这些需要Bean类自身去实现的接口，它们提供了对Bean生命周期特定阶段的感知能力。",
    "source": "文档中「SpringBean生命周期函数分类」的「Bean级生命周期的方法」部分",
    "hint": "思考一下这些接口是作用于Bean本身，还是作用于整个容器或工厂？"
  },
  {
    "question": "根据文档内容和代码示例，`BeanPostProcessor`接口的主要作用是什么？",
    "options": [
      "在Bean实例化之前修改Bean的定义信息（BeanDefinition）。",
      "在Bean初始化（Initialization）阶段前后提供扩展点，允许对Bean实例进行加工处理。",
      "仅在容器关闭时被调用，用于统一销毁所有Bean。",
      "负责根据XML配置文件或注解来创建Bean的实例。"
    ],
    "correctAnswerIndex": 1,
    "explanation": "`BeanPostProcessor`接口，通常被称为后处理器，是容器级的扩展点。它定义了`postProcessBeforeInitialization`和`postProcessAfterInitialization`方法，允许开发者在任何Bean的初始化回调执行之前和之后，插入自定义逻辑，例如创建代理对象（AOP的实现基础）。",
    "source": "文档中「SpringBean生命周期函数分类」的「容器生命周期方法」和「代码演示生命周期」部分",
    "hint": "这个接口的名字直译为“Bean后置处理器”，暗示了它的工作对象是已经创建的Bean实例。"
  },
  {
    "question": "文档中的`MyBeanFactoryPostProcessor`示例展示了`BeanFactoryPostProcessor`的一种用法，它的执行时机和作用是什么？",
    "options": [
      "在所有Bean实例化之后，对所有Bean的属性进行批量修改。",
      "在Bean实例化之前，读取并修改Bean的配置元数据（BeanDefinition）。",
      "在特定的Bean（如'person'）初始化之后，为其创建一个代理。",
      "在Spring应用上下文关闭时，执行资源清理工作。"
    ],
    "correctAnswerIndex": 1,
    "explanation": "`BeanFactoryPostProcessor`是一个非常强大的容器扩展点。它在Spring容器加载了所有Bean的定义信息（BeanDefinition）之后，但在任何Bean实例被创建之前执行。这使得我们有机会在Bean实例化之前，以编程方式修改这些定义，如示例中修改了`person`的`phone`属性值。",
    "source": "文档中「代码演示生命周期」的「后置处理器接口方法」部分",
    "hint": "请注意这个接口名称中的 'BeanFactory'，它表明其操作目标是Bean工厂本身和Bean的定义，而不是已创建的Bean实例。"
  },
  {
    "question": "在文档展示的 `Person` 类的代码中，哪两个方法分别是通过实现标准接口和通过XML配置来定义销毁逻辑的？",
    "options": [
      "`afterPropertiesSet()` 和 `myInit()`",
      "`destroy()` (实现DisposableBean) 和 `myDestory()`",
      "`setBeanName()` 和 `destroy()`",
      "`myInit()` 和 `myDestory()`"
    ],
    "correctAnswerIndex": 1,
    "explanation": "在`Person`类中，`destroy()`方法是通过实现`DisposableBean`接口来定义的销毁回调。而`myDestory()`方法则是在`beans.xml`文件中通过`<bean>`标签的`destroy-method`属性指定的自定义销毁方法。两者都是在容器关闭、Bean被销毁时调用的。",
    "source": "文档中「代码演示生命周期」的「Bean自身的方法和Bean级生命周期接口方法」和「配置文件如下beans.xml」部分",
    "hint": "请在`Person.java`代码中寻找实现了`DisposableBean`接口的方法，并在`beans.xml`中寻找`destroy-method`属性。"
